Floribunda rose plant named `Interbab`

ABSTRACT

A floribunda rose variety producing yellow flowers.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct floribunda rose variety which was originated by my crossing an undistributed seedling as seed and as pollen parent the variety known as `Carte d 'Or.` The varietal denomination of this new rose is `Interbab`.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by the new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive, yellow flowers borne in sprays on a bushy, vigorous plant.

Asexual reproduction by budding of the new variety as performed in Watsonville, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. Other known forms of asexual reproduction for roses, may be also employed.

Comparison with Parents

The new variety differs from the female parent by, among other characteristics, in producing flower sprays with longer and stronger stems and from the male parent by having smaller flowers, different flower color and more flower spray production.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration show typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
